Analysis Methods for Poor Peel Strength Issues
In the performance evaluation of laminated packaging films, peel strength is one of the most critical indicators. During the processing and application of laminated films, "poor peel strength" is a frequently encountered problem. Through summarization and induction, feedback regarding "poor peel strength" from customers and downstream users can be categorized into two types: "Below Design Value" Type: The measured peel strength is lower than the designed or planned value. "Unsatisfied Application Requirements" Type: The peel strength is inferred to be non-compliant based on other observed phenomena. I. Essential Knowledge and Skills Before Analysis Prior to analyzing poor peel strength, one should master the following: Orientation Identification: Correctly judging the relationship between the length/width of the pouch and the machine direction (MD) / transverse direction (TD) of the film. Geometric Dimensions: Including design/nominal size, ...
